AMD Ryzen 8000 “RDNA3.5” initial support integrates with upcoming Mesa 23.3

Initial support AMD RDNA3+ merges with Mesa 23.3

AMD Navi 3.5 architecture now part of the upcoming open-source graphics core for Linux. 

Progress in RDNA3 architecture support for Linux environment is advancing rapidly. The Mesa 23.3, an important component in the open-source graphics ecosystem for Linux, will soon integrate the GFX11.5/Navi3.5 architecture, also known as RDNA3.5 or RDNA3+. Recent patches were successfully merged today, signaling an important milestone in the development of this new architecture.

Mesa, serving as an open-source software implementation of OpenGL, Vulkan, and various other graphics API specifications, is a critical component for Intel and AMD graphics hardware support on Linux. Both companies have engineers working on preparing new hardware for upcoming releases, with a strong focus on integrated graphics, next-generation desktop and mobile GPUs, and CPUs.

The GFX 11.5 architecture elements remain consistent with its predecessors. The current iteration of RDNA3 already laid the groundwork for the refresh. Thus, the development of this new architectural update draws extensively from GFX11.0, notes Phoronix.

This architectural update is reportedly geared towards the upcoming Ryzen 8000 “Strix” APU line, which has been confirmed to incorporate the Navi 3.5 architecture. AMD has maintained a tight lid on specific details regarding the enhancements brought by this refresh in comparison to the existing architecture.

Nonetheless, there is anticipation that the Ryzen 8000 APUs will boast an increased number of Compute Units, potentially reaching 16, as opposed to the current series, which comprises 12. The announcement of this new Ryzen series is projected to occur early next year, with its launch scheduled to closely follow Intel’s release of the Core Ultra 100 “Meteor Lake” in mid-December.
